Yibin Tianyuan announced that its subsidiary, Infinity Mining's phosphating plant, stopped production on December 19, 2023. In order to revitalize idle intangible assets, the company publicly listed and transferred the 25,000 tons/year yellow phosphorus production capacity target, and eventually Hebang Biotech sold it for 185 million yuan. On November 25, 2025, the two parties signed a “Property Exchange Contract”, and Hebang Biotech will pay within 5 working days of the contract's entry into force. The transfer still needs to be announced by Mabian County on the withdrawal of the yellow phosphorus production capacity of Infinity Mining before the delivery can be completed. There is uncertainty. The transfer did not constitute a major asset restructuring and had no significant adverse impact on the company's financial and other indicators.
